10 Claims.

My invention relates to an improvement in fruits, vegetables or othercommodities.

My invention has for an object the provision of an improved carton welladapted for use in the packaging of apples, peaches, pears, or otherfruits or vegetables, and other uses in which a strong, rigid and lowcost container, which is light in weight, is desired.

My invention contemplates a carton, as a new article of manufacture,made from a plurality of plies of single-faced corrugated board and soassembled in the carton to provide bottom andwalls of double-facedcorrugated board.

In the drawings accompanying and forming a 4 part of the specification Ihave illustrated a form and manner in which my invention may be utilizedand embodied. In the drawings,

Figs. 1, 2 and 3 are sectional views on an enlarged scale of types ofcorrugated boards in common use;

Fig. 4 is a plan view of a blank made from single-faced corrugatedboard, cut and creased and adapted to be folded into the carton shown inFig. 5;

Fig. 5 is a perspective view of'my improved carton with one portion cutaway to show the ,sectional construction; and

Fig. 6 is a plan view of a reenforcing blank.

Corrugated fibre board is manufactured in several type' constructionsamong which is the type known as single-faced corrugated boar whichcomprises a single facing of solid flat board, on one side of which isattached a corrugated or fluted board. This type is shown in Fig. 1 inthe drawings. A second type of double-faced corrugated boar whichcomprises two facings of solid flat board, each attached to oppositesides of a corrugated or fluted board. This type is shown in Fig. 2 inthe drawings. A third type is double-strength corrugated board whichcomprises a double-faced corrugated board to one side of which isattached a single-faced cormgated board or, in other words, twosingle-faced corrugated boards attached to opposite sides of a centerflat board. This type is shown in Fig. 3 of the drawings.

Referring to Fig. 1, numeral l0 represents a facing liner and II thecorrugated sheet which is attached thereto. In Fig. 2, I2 and I3represent the facing liners and M the corrugated sheet which is fixedbetween them. In Fig. 3, I5 and I6 represent the facing liners, I! thecensheets.

In Fig. 4 I have shown one form of blank which is adapted to carry outmy invention, but it will be obvious that other forms may be used toadvantage. This blank is made from a sheet of single-faced corrugatedboard of the type shown in Fig. 1. It is cut on the full lines andcreased or scored on the broken lines. Numeral 20 is the outer bottommember and 2| is the inner bottom member. The outer end wall members 22and 23 are attached to the bottom member 20 and carry at their end thecorner pieces 24, 25, 26 and 21. The outer sidewall members 28 and 29are likewise attached to the outer bottom member 20. The inner end wallmembers 30 and 3| are attached to the inner bottom member 2| and theinner side wall .member 32 connects the inner bottom member 2| to theouter side wall member 29. The inner side wall member 33. is attached tothe inner bottom member 2| and carries the flap 34 to which is attachedthe flap 35. These flaps 34 and 35 serve as looking means to hold thecarton in set-up position.

- The cover 36 is provided with the fianges3'l, 38 and 39 and isattached to the outer wall member 28.

To set up the carton from the blank shown in Fig. 4 the blank is placedwith the corrugated side up. The outer end wall members 22 and 23 arebrought up to position and at the same time the corner pieces 24, 25, 26and 21 are turned at right angles to the outer end wall members. Theinner bottom member 2| is now brought over so as to superimpose upon theouter bottom member 20 and this will cause the side wall members 29 and32 to overlap the corner pieces 24 and 25. The inner side wall member 33will be within the corner' pieces 26 and 21. The flap 34 is now foldeddown over the corner pieces 26 and 21 and the flap 35 is tucked betweenthe bottommembers 20 and 2| and serves to hold the carton in erectedposition. I

The partition members 40 and 4| are now brought up to stand at rightangles to the bottom of the carton and serve as cushion separators forrows of apples or other articles which may be bruised or damaged bycontact with each other when packed in the carton.

Though I have shown the cover 36 in connection with the blank of Fig. 4it will be obvious that the cover is not an element of nor is itnecessary to carry. out my invention in practice, If a cover is not usedwith the blank shown in Fig. 4 the outer wall 28 may be secured to theter sheet and I8'and I9 the two corrugated inner wall 33 by stitching orotherwise. The flap 35 would not be necessary, since its function is tohold the box erected until the cover is brought into closure position.

After the carton has been packed, the cover 36 may be brought intoclosure position, the flanges 31 and 38 being preferably tucked withinthe carton and the flange 39 without the carton and the carton sealed bya corner stitch, a gummed paper seal or other means.

If desired, some form of adhesive, like silicate of soda, may be coatedor brushed over the corrugations before the blank is folded. If .acarton of greater strength is desired, a reenforce, such as that shownin Fig. 6, may be inserted between the plies of the carton. As shown,the reinforcing or lining member of Fig. 6 comprises a central panel 50adapted to lie between the members 20 and 2| of the finished carton, andside panels 5|, 52, 53 and 54 adjoining the panel 50 along score linesdefining the latter. Thus, in the finished carton, the panel 54 may liebetween the members 20 and 29.

While the reinforcing member may be made i of singleor double-facedcorrugated board, I prefer to form it from uncorrugated facing paper. Bycovering the sides of the reinforcing panel with adhesive and theninserting it while forming the carton, the result is secured that thesides of the carton are formed of the double strength corrugated boardshown in Fig. 3, although the blank therefor is made of simplesingle-faced corrugated board as illustrated in Fig. 1. It furtherresults that the carton thus formed is extremely rigid, strong anddurable, considerably more so in fact than if no reinforcing panel wereused but the blank were initially made of double-strength corrugatedboard as illustrated in Fig. 3.

A modification of my invention comprises the two blanks. This may beaccomplished by making the series of members forming the outer walls,

and bottom of one type of stock and the series of members forming theinner walls and bottom of a different type of stock. For example, if theouter series is made of liner or facing stock and the inner series ofsingle-faced corrugated stock, after folding and assembling we, willhave a box which will correspond to a box made of one ply double-facedcorrugated board, except it will be of more pleasing appearance.

After the box has been erected it will be noted that the cross sectionthrough the walls or bottom will correspond to single-ply corrugatedboard. Thus if the two series of members are made from singIe-facedcorrugated board we will have a section similar to a double-facedcorrugated board as shown in Fig. 2 with the addition of an extracorrugated sheet. If one series of members is made from facing or linerstock and the other from single faced corrugated board we will .have asection similar to the double-faced corrugated board shown in Fig. 2. Ineach case the interior surface and the exterior surface of the box willbe flat or smooth, the corrugations being concealed between the facings.

My invention provides for the manufacture of bodied within the scope ofthe claims hereinafter made.

I claim:

. corrugations of each series being positioned between the facings ofthe two series in the finished box, both series of members being formedfrom a unitary blank. I

3. A box comprising two connected series of members to form a pluralityof layers in the walls and bottom of the box,each series of membersbeing, made from single-faced corrugated board, and each series ofmembers being folded to position the corrugations between the facings inthe erected box.
